| To R.{Sir Henry Royce} [struck through] From Hs.{Lord Ernest Hives - Chair} c. to SG.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} [struck through] c. to E.{Mr Elliott - Chief Engineer} BA. [struck through] c. to SY. [struck through] [Handwritten]: X7380 [struck through] X7770 [struck through] X1698 'SS{S. Smith}' CARS. Since we sent 21-EX car to Sales we have been able to affect definite improvements to the SS.{S. Smith} cars at Derby by giving attention to the detail mounting of the subframe. By this means we have been able to reduce the resonance in the body to a considerably extent. We are still however not satisfied with the amount of noise and fumes which can be heard in the driving seat - in this respect we think we midgets [struck through] are worse than the Phantom and are now giving our attention to [handwritten 'to' above 'this'] this. By the end of this week we hope to have two SS.{S. Smith} cars which will represent the standard we might expect from production. [Handwritten]: would like to carry We propose carrying [struck through] out comparative tests with these cars against a standard Phantom Trials car - if they are then considered unsatisfactory, we propose bringing the Phantom and SS.{S. Smith} cars to WW. so that we can go over the various points with you. We should like Sg.{Arthur F. Sidgreaves - MD} to arrange a meeting place for the cars on Monday the 8th., and if necessary we could be at WW. on Tuesday the 9th. Hs.{Lord Ernest Hives - Chair} | ||
